Abstract

On the transmission side it is possible, in addition to the basic teletext data from conventional teletext pages, to transmit supplementary data for a teletext page in the form or one or more associated supplementary pages, with pages numbered in the hexadecimal system, structured in the format of original teletext pages and stored temporarily on the reception side separately from the basic data of a desired teletext page. The numbers of the supplementary pages coded in the hexadecimal system outside the decimal system are related, according to a fixed system, to the numbers of the associated conventional teletext pages numbered in the decimal system and selectable via the ten-key keypad. To facilitate compatible transmission of teletext pages for 16:9 aspect ratio screens, further supplementary data with an independent image content are transmitted instead of or in addition to the supplementary data, in the same code and format. The further supplementary data are displayed on a screen with a 16:9 aspect ratio in the image field alongside a conventional teletext page or alongside a conventional television picture having a 4:3 aspect ratio.

Description

Die Erfindung bezieht sich auf ein Verfahren gemäß dem Oberbegriff des Patentanspruchs. Ein derartiges Ver­ fahren ist aus der DE 39 14 697 A1 bekannt.The invention relates to a method according to the Preamble of the claim. Such a ver driving is known from DE 39 14 697 A1.

Bei dem herkömmlichen, derzeit in Europa (mit Ausnahme von Frankreich) benutzten Teletextsystem wird der sog. "Level 1" des Teletext-Standards WST (World System Teletext) benutzt, welcher Texte und graphische Dar­ stellungen mit eingeschränktem Grundzeichensatz auf einem Bildschirm mit dem Seiten-Höhen-Format 4 : 3 dar­ stellt. Sonderzeichen, Feinstrukturen und Farbschattie­ rungen sieht der WST-Standard in seinen Ausbaustufen "Level 2" und "Level 3" vor, wobei die Übertragung von Ergänzungsdaten in sog. Pseudoreihen (auch "ghost rows" genannt) erfolgt, welche vom "Level 1" nicht ge­ nutzte, jedoch im Übertragungsformat freigehaltene, adressierbare Reihennummern tragen. Bei Bedarf müssen mehrere Reihen mit derselben Reihennummer zur Übertra­ gung der notwendigen Menge von Ergänzungsdaten ver­ wendet werden, wie anhand von Fig. 1 für die Reihen­ nummer #26 veranschaulicht ist (vgl. "Rundfunktech­ nische Mitteilungen" 27. Jg. (1983), Heft 3, S. 116 bis 134). Da der Teletext-Empfänger keine Information über die Anzahl der jeweils zu einer Teletextseite (Grund­ daten) übertragenen Pseudoreihen erhält, "weiß" der Decoder nicht, ob, welche und ggf. wieviele Pseudo­ reihen zu einer Teletextseite ausgesendet worden sind. In the conventional teletext system currently used in Europe (with the exception of France), the so-called "level 1 " of the teletext standard WST (World System Teletext) is used, which texts and graphic representations with a limited basic character set on a screen with the page - Height format 4: 3 represents. The WST standard provides special characters, fine structures and color shading in its expansion levels "Level 2 " and "Level 3 ", whereby the transmission of supplementary data takes place in so-called pseudo-rows (also called "ghost rows"), which are provided by "Level 1 " wear unused, but addressable row numbers in the transmission format. If necessary, several rows with the same row number must be used to transmit the necessary amount of supplementary data, as illustrated with the help of FIG. 1 for row number # 26 (cf. "Broadcasting Technical Messages" 27th vol. (1983), Issue 3, pp. 116 to 134). Since the teletext receiver does not receive any information about the number of pseudo rows transmitted to a teletext page (basic data), the decoder does not "know" whether, which and possibly how many pseudo rows have been sent out to a teletext page.

Eine korrekte Auswertung kann daher nur dann erfolgen, wenn die gewünschte Teletextseite und alle zugeordne­ ten Pseudoreihen vollständig empfangen werden. Ferner muß in dem Decoder für jede abzuspeichernde Teletext­ seite ein zusätzlicher Speicherraum, z. B. 4 kByte, ständig verfügbar gehalten werden, welcher bei fehlen­ der Übertragung von Pseudoreihen nicht anderweitig nutzbar ist.A correct evaluation can therefore only take place if if the desired teletext page and all assigned th pseudo series are received completely. Further must be in the decoder for each teletext to be stored an additional storage space, e.g. B. 4 kbyte, constantly available, which one is missing the transfer of pseudo series not otherwise is usable.

Um eine effizientere Übertragung und schnellere Ver­ arbeitung der Ergänzungsdaten zu ermöglichen, ohne die volle Kompatibilität zu bestehenden, nach "Level 1" arbeitenden Teletextempfänger zu verlieren, ist es aus der DE 39 14 697 A1 bekannt, zusätzlich zu herkömmlichen Teletextseiten ("Grundseiten") sogenannte Ergänzungs­ seiten zu übertragen, die vorzugsweise im Format der Teletextseiten strukturiert sind. Wie Fig. 2 zeigt, ent­ halten die zu einer bestimmten Teletextseite zugeordne­ te(n) Ergänzungsseite(n) die für einen höheren WST-Level (z. B. Level 2/3) fehlenden Daten ("Ergänzungs­ daten").In order to enable more efficient transmission and faster processing of the supplementary data without losing full compatibility with existing teletext receivers operating according to "Level 1 ", it is known from DE 39 14 697 A1, in addition to conventional teletext pages ("basic pages") so-called supplementary pages to transmit, which are preferably structured in the format of the teletext pages. As shown in FIG. 2, the supplementary page (s) associated with a specific teletext page contain the data missing for a higher WST level (eg level 2/3 ) (“supplementary data”).

Im Empfänger werden Grunddaten und Ergänzungsdaten von dem Videosignal abgetrennt und zu jeweils einer Teletextseite auf einem Bildschirm mit einem Seiten- Höhen-Format 4 : 3 zusammengestellt. Bei einem Bild­ schirm mit einem erweiterten Seiten-Höhen-Format von 16 : 9 ist die Darstellung von Teletextseiten im 4:3- Format aber nur unbefriedigend möglich, da entweder bei unverzerrter Darstellung ca. 40% des 16 : 9-Bild­ schirms ungenützt bleiben (sh. Fig. 3) oder bei ent­ sprechender formatfüllender horizontal gestreckter Darstellung nicht akzeptierbare Verzerrungen des Gesamtbildes auftreten (Fig. 4).In the receiver, basic data and supplementary data are separated from the video signal and compiled into a teletext page on a screen with a page height format of 4: 3. With a screen with an expanded page height format of 16: 9, the display of teletext pages in 4: 3 format is only unsatisfactorily possible, since approx. 40% of the 16: 9 screen remains unused if the display is undistorted (see FIG. 3), or with unacceptable distortions of the overall image when the format is stretched horizontally to stretch ( FIG. 4).

Es ist ferner aus der DE 39 12 805 A1 bekannt, auf einem Breitbildfernsehschirm die Teletextinformationen im her­ kömmlichen Seiten-Höhen-Format von 4 : 3 darzustellen und die freien Flächen an den Rändern des Breitbildfernseh­ schirms für die Darstellung von Benutzerführungsinforma­ tionen zu verwenden. Darüber hinaus ist es auch schon bekannt (DE 39 23 907 A1), Teletextsignale und Video­ signale gleichzeitig nebeneinander auf einem Bildschirm darzustellen.It is also known from DE 39 12 805 A1, on a Widescreen TV screen in the teletext information conventional page-height format of 4: 3 and the free areas on the edges of the widescreen television screens for the display of user guidance information to use. In addition, it is already known (DE 39 23 907 A1), teletext signals and video signals simultaneously side by side on one screen to represent.

Die Aufgabe der Erfindung besteht demgegenüber darin, eine kompatible Übertragung von Teletextseiten für 16 : 9-Bildschirme zu ermöglichen.In contrast, the object of the invention is a compatible transmission of teletext pages for Allow 16: 9 screens.

Diese Aufgabe wird erfindungsgemäß durch die kenn­ zeichnenden Merkmale des Patentanspruchs gelöst.This object is achieved by the kenn Drawing features of the claim solved.

Die Erfindung wird anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert. Es zeigt:The invention is based on one in the drawings illustrated embodiment explained in more detail. It shows:

Fig. 7 example of the use of a 16: 9 widescreen screen by a conventional television picture in 4: 3 format and an additional additional teletext field.

Bei dem erfindungsgemäßen Verfahren werden zusätzlich zu den herkömmlichen Teletextseiten ("Grundseiten") und den Ergänzungsseiten mit den für einen höheren WST-Level fehlenden Daten weitere Ergänzungsdaten zur Darstellung eines Zusatzfeldes auf den 16 : 9-Breit­ bildempfänger übertragen (sh. Fig. 5).In the method according to the invention, in addition to the conventional teletext pages (“basic pages”) and the supplementary pages with the data missing for a higher WST level, additional supplementary data for displaying an additional field are transmitted to the 16: 9 wide image receiver (see FIG. 5) .

Während herkömmliche Decoder durch die 4 : 3-Bildschirme auf jeder Seite nur 24 Reihen mit 40 Zeichen darstellen können, ist bei zukünftigen 16 : 9-Bildschirmen die An­ zeige einer Fernsehseite aus 24 Reihen mit beispiels­ weise je 40+16 Zeichen möglich. In diesem Zusatzfeld, das aus 24 Reihen mit je 16 Zeichen besteht,können beispielsweise neben Textinformationen auf der 4 : 3- Seite weitergehende erklärende Grafiken und Bilder dargestellt werden (sh. Fig. 6).While conventional decoders can only display 24 rows with 40 characters due to the 4: 3 screens on each side, in future 16: 9 screens it is possible to display a TV page from 24 rows with, for example, 40 + 16 characters each. In this additional field, which consists of 24 rows with 16 characters each, in addition to text information, further explanatory graphics and images can be shown on the 4: 3 page (see FIG. 6).

Die Ergänzungsdaten für das Zusatzfeld sind ähnlich codiert und formatiert (beispielsweise entsprechend der CEPT-Videotex-Codierung) wie die Ergänzungsdaten für die höheren Level.The supplementary data for the additional field are similar encoded and formatted (e.g. accordingly the CEPT-Videotex coding) as the supplementary data for the higher levels.

In Empfängern mit 16 : 9-Bildschirmen werden die mittels Ergänzungsseiten übertragenen Ergänzungsdaten für das Zusatzfeld und für die höheren Level zusammen mit den Grunddaten ausgewertet und zu einer Teletext­ seite mit 56 Zeichen pro Reihe dargestellt, während die herkömmlichen Empfänger nur die Grunddaten gegebenenfalls zusammen mit den Ergänzungsdaten für höhere Level auswerten und auf dem 4 : 3-Bildschirm darstellen.In receivers with 16: 9 screens, the means Supplementary data transmitted for supplementary pages for the  Additional field and for the higher levels together with the basic data evaluated and a teletext page shown with 56 characters per row, while the conventional recipients only the basic data if necessary together with the supplementary data for evaluate higher levels and on the 4: 3 screen represent.

Fig. 7 zeigt eine weitere Anwendung für das erfindungs­ gemäße Zusatzfeld auf, mit der die bei Darstellung von FS-Programmen im 4 : 3-Format auf Bildschirmen im 16 : 9-Format entstehenden, nicht benutzten Bereiche sinnvoll genutzt werden können. So können beispiels­ weise eine Programmvorschau oder weitere Zusatz­ informationen (hier ein Aktienindex) durch entsprechend ausgerüstete Decoder auf einem 16 : 9-Bildschirm neben dem 4 : 3-Bild des laufenden FS-Programms auf dem Zusatz­ feld dargestellt werden. Fig. 7 shows a further application for the additional field according to the invention, with which the unused areas which arise when displaying FS programs in 4: 3 format on screens in 16: 9 format can be used in a meaningful manner. For example, a program preview or other additional information (here a share index) can be displayed on the additional field on a 16: 9 screen next to the 4: 3 picture of the current FS program using suitably equipped decoders.
